Data Engine Error 4: File Used by Other Process

Issue

During an extract refresh, the following Tableau Desktop error occurs while communicating with the data source:

Tableau Data Engine Error: 4: The process cannot access the file because it is being used by another process.

Environment

Tableau Desktop

Resolution

Complete the following steps as appropriate:

  • Make sure that no other open Tableau Desktop sessions are using the same extract file as a primary data source.
  • Verify that the .tde file itself is not open or in use, including in another Tableau workbook by another user. If the file is on a network share, make sure no other users are connected to the file.
  • Restart the computer and try the refresh again. Restarting the computer might resolve any latent file locks

Cause

Another Tableau Desktop session is open at the same time and connected to the extract (*.tde) file. The existing session has a lock on the file, so you are unable to perform the refresh from a different Tableau Desktop session.
